Silver and Carbon – Natural Water Purification Technologies

Silver ions (Ag+) kill harmful micro-organisms even when the concentration is quite low. Silver is a good bactericide and produce bactericidal and algaecidel effect. Silver ions destroy and block the enzymes that bacteria and other microorganisms use to “breathe” and live on.
When the silver reacts with air (oxygen that water partially consists of) it forms silver oxide. This byproduct is also a bactericide. Silver oxide can kill primitive life form as successfully as chemical disinfectant. But what makes silver a better variant is that silver is quite harmless to mammals. Besides silver doesn’t make any harm to our environment.

Silver disinfectants are able to keep water safe to drink for a long period of time. Thereby this technology is widely used in the space station where it’s necessary to maintain the quality of water for a long period.

The amount of silver used in water filters is so small that any possible harmful impact it produces is equivalent to that of the silver cutlery.

Another natural element that is used in water purification technologies is carbon. Carbon that is embedded into the water filters is received from different raw materials (bituminous coal, coconut shells, etc). While other organic chemicals threaten our health active carbon being absolutely health produces the same adsorbing effect.
The surface of the activated carbon is hydrophobic. It means that under suitable condition water flows near the activated carbon surface freely. At the same time chemicals and other substances stick to the surface and form a thin film. This process is called adsorption.
Using this water purification technology chlorine, pesticides and other substances that spoil the taste and odor of the water are eliminated. The adsorption takes place on a large surface area of the activated carbon. To understand how large the activated carbon surface is you can imagine a teaspoon of carbon and then a football field: their surface areas are equal in size.
